The best calendar app I have found! Easy to set up and has no problem syncing up my Android, my iOS and my Windkws 10 phones and PC perfectly! I have been struggling with calendar synchronization problems for 3 months and this app installed on my phone and on my PC solved everything!
This is an awesome calendar! Easy to use, fast to sync and organize! Love it!! Thank you for the great work! You save so much pain!
Unbelievable that this is free. NO ads. Tried many apps before I found this one which syncs beautifully with iOS calendar . VERY customisable, great UI - especially the brilliant 'listview'. Well done and thanks
